What is the difference between external commutation and self-commutated inverters?
The external commutation inverters, acquire sources externally from motors or power supply and the self-commutated inverters control the circuit with the help of capacitor function. Self-commutated inverters are classified as current source inverters and voltage source inverters. This article gives an overview of a voltage source inverter.
What is load commutated inverter fed synchronous motor drive?
Load Commutated Inverter Fed Synchronous Motor Drive is shown in Fig. 10.22. The inverter is a current source inverter employing thyristors T 1 – T 6. The commutation of inverter thyristor is done by the voltages induced in armature of the synchronous motor. A chopper is used to obtain a variable dc voltage V ds from the fixed source voltage V.
What is commutation of inverter thyristor?
The commutation of inverter thyristor is done by the voltages induced in armature of the synchronous motor. A chopper is used to obtain a variable dc voltage V ds from the fixed source voltage V. The V ds is varied with V dl so that a required current is supplied to the dc link, and therefore, to the motor.
